Tronxy X3a Y Motor mount flipped for Upgrade Bed

thingiverse

This is a work-in-progress design I haven't fully tested yet. This Y motor mount is modified to be compatible with Bed Upgrade parts and uses the original T-nuts screws and motor mount screws. The top and side are 3mm thick, while the angle supports are 4mm thick. There's some room between the angle brackets for air flow cooling. I based this design on Create3DPrints' TronXY X3 X Motor Mount, which provided a solid foundation for my modifications. After printing, you'll notice that the screw holes are slightly off-center. To fix this issue, start by cleaning up the inside corners and surfaces of the part. Then, align the first hole and mark its direction on top of the part with a pencil. Use a 4mm drill bit to slowly work the hole open by moving it back and forth while applying pressure in the correct direction. Repeat this process for each hole, continually checking alignment and making adjustments as needed. The large central hole needs to be trimmed back on the first side where the screw is located. Use a razor blade to carefully remove material until the motor sits flush with the top surface. In most cases, only three holes are slightly off by about 1mm. To avoid frustration, work one opening at a time and frequently check alignment by installing the motor. I didn't discover this information before creating my design, but kencam on Thingiverse has a Y motor mount specifically designed for Bed Upgrade parts (thing:2185364). This part likely has perfectly positioned screw holes, making it a better option than dealing with post-production adjustments.
